[QUOTE="IWT, post: 1325745, member: 83420"] Good Morning (here in the UK anyway) You don't say what OS you are running. If Snow Leopard (10.6.8) then see below. If Lion (10.7.2), then others need to help you as I haven't yet upgraded to Lion. If the iMac is so new and runs on SL, you must have the original Disks that came with it, two in number. If you put Disk 1 in the tray and boot holding down the "C" key you should be able to boot up from the Disk (instead of your computer's Int HD). If you succeed, select "Utilities" from the Toolbar, then "Disk Utility". Now carry out the following - First "Verify Disk", then, if prompted, "Repair Disk". This process checks for corrupted files and other problems related to the iMac's Int HD as well as verifying the integrity of the Disk as a whole. Next, you could try "Repair Disk Permissions". What you do next depends on the results of your endeavours. All may be fixed and you can reboot in the normal way. Or, there mat be an unrepairable Disk problem. Or, you might need to re-install your OS X software from your Optical Drive Disk. So, I suggest you carry out the first parts mentioned at the top and let us know what the results are. Sorry if you're on Lion because what I've suggested won't help, but it's the best I can offer. Ian [/QUOTE]
